IMPROVEMENT iN APPARATUS FOR VENTILATING RAILROAD-CARS.

Specification forming part of Letters Patent No. 52,009, dated anuavr'y9, 18.66.

To all whom 'it may concern: A y Be it known that I, H. JONES RUTTAN, ofj Cobourg, in the county of Northumberland and `i Province of CanadaWfest, have made new and useful Improvements in the Ventilation ofRailroad-Cars; and I do hereby declare the i following to be a full,clear, and exact descrip- ,tion ofthe nature, construction, andoperation of the same, sufficient to enable one skilled in the art towhich it appertains to construct and juse the same, reference being hadto the accompanyin g drawings, which are made part of i T thisspecification, and in which- Figure l is au isometric perspective view,a portion of the root' and one side of the car being removed. Fig. 2 isan isometric view of the heating-stove attached to one ot' theinlet-apertures of the car. Fig. 3 is a view of one of i the receivingcaps or funnels to inhale the air, and Fig. et is a vertical chambers inFig. 4.

My improvements consist, tirst, in the ar-l rangement ot' the inlet andexit air-chamber, with the water-tanks for purification at the ends ofthe car; second, in the mode ot delivery of the puriiied air into thecar; third, in the mode of withdrawing the impure air from the saloon ofthe carpfourth, in the arrangement of the air-warmer, in connection withthe v inlet air-chamber.

There are several requisites to the effectual and convenient ventilationof railroad-cars, among which may be mentioned, first, the abundance,purity, and moisture and agreeable temperature of the air 5 secondly,economy of construction and freedom from liability to get out of order;thirdly,`convenience of location, leavin g the central and mostdesirable portion of the car free from obstruction; fourthly, such adelivery of the air as shall be most conducive to the comfort of thepassengers and most .effective in securing a supply of wholesome air toevery part of the car.

- The railroad-car represented in Fig. 1 ofthe drawings has a portion ateach end of the car on each side of the dooroccupied by the devices forthe inlet and exit air-chambers. A portion of the root` of the car isshown at l, and above this'are the air-recei ving caps m m, which havefunnel-shaped openings forward or backward for the purpose of collectingthe air as the car noves or as the wind blows in such a direcsectionthrough the tion as to be inhaled by` their open'niouths.

Pointing in each direction of the cars motion, they are adapted togather in the air, opening the valve p or pf, Fig. 3, according to thedirection of the entering-air, and closing the valve opposite to theentrance. The incoming air is then deflected downwardly into the trunkb, at thc bottom of which is a tank of water of a few inches depth-sayfrom six to eightand after coming in contact with the water is thenreceived upwardly around the lower edge of the plate, which divides thedowncast trunk b and the upward cast d. The water splashing about in thetank makes the contact of the water still more decided and complete, andthe water becomes possessed of the flying particles mechanicallysuspended in the air, and imparts to the air a freshness and puritywhich form an agreeable contrast to its former aridity and fonlness.After undergoing this purification in the entrance-trunks the air isintroduced in the saloon of the car through the entrances f at a heightwhich causes it to visit tirst the faces of the passengers, which is byall odds the most felicitous mode of application, the various contrivances which bring the blast from below keeping the dust in a turmoiland reaching the respiratory organs freighted with the odor ot' theinevitable concomitants of a public door.

In my arrangement the air introduced at the openings j' f, aftercirculating through the upper portion of the saloon, descends to thelower regions, and reaches the recesses under the floors q on each sideot' the aisle. Openings k for this purpose are left under one of theseats on each side of the aisle, and the air, finding its way under theiioor qand between that and the lower flooring-boards of the car, isconducted toward each end to the upcast chutes o, which occupy thecorners ofthe car, and thence tinds its exit at a cowl-chimney or otheropening in the roof.

In winter time, .or at other times when artiticial heat is required, theair in the upcast chamber, d, (see Fig". 2,) instead of being introducedinto the saloon through openings j', is conducted by a spoilt, g, to aWater and air chamber, 71 under a stove, which latter is provided withtubes, through which the air is passed before entering the saloon,receiving in its passage such an increment of heat as may be judiciousand comfortable. As many of the corners may be thus provided withheaters as may be necessary to accomplish the purpose of Warming theinterior of the car.

The transverse sectional 'area of the chambers b d, collectively, may bethirty-three by twenty-four inches, divided equally between them, thetop of the inner chamber or upcast shaft only coming` to the root',While the shaft b, penetrating the roof, is capped by the receivers m am.

The description ot' one corner answers for each of the others.

Suitable arrangements are made for the introduction of Water into thetank, which occupies the lower portion of the chamber b d, and for itsdischarge when necessary. rlhe former is obtained by the door J, Fig. 2,and the latter by a plng in the iioor of the tank, which may be reachedfrom below, or through the doei1 J.

Having described my invention,l what I claim therein as new, and desireto secure by Letters Patent, is-

1. The arrangement of the inlet andvexit chambers b, d, and o, Withthe'water-tank at the ends ot' the car, as and for the pnrp'osedcscribed. f

i?. The combination of the chambers b d, divided by a partition, andtheir lowerv portion forming a tank, as described.

3. The mode of withdrawing the impure air by openings in the floorleading to an upcastshaft delivery above the roof.

4. In combination with the shafts b d, the 'v
